I use vinegar (white - 5% acidity) and have no problems with stability. Let me get real specific so others get an idea of what I am working with rather than just saying, "I use vinegar". I have 5 gallon buckets with 8" net pots. It takes 3 gallons of liquid to get the level to the bottom of the net pot. The solution/nutes is a combination of water, SMS-90, and Regen brand "Grow" (). I use "Grow" because I know the guy that makes it and they make it on site in my area. I am lazy and don't own a R/O filter and don't bother with letting jugs of tap water sit for 24-48 hours before using.I've heard lemon juice and I've heard vinegar and I've heard people say the used it and it didn't work. Are you speaking from experience or from hearing. Do you use pure lemon juice? I've heard the store bought lemon juice ain't worth a shit. I would like to know from somebody that actually uses it
so long as its not malt its good mate. i have personally used organic Brown Rice Vinegar, and Apple Cider Vinegar as a solvent. It works extremely well and can be made by anyone with Google and time and a few low cost components.I use vinegar (white - 5% acidity) and have no problems with stability.

About once a week, I change out the bucket. To do so, I lift the growing plant/net pot out, put it on top of an empty bucket, drain the bucket, clean, put it back in the growing area and make another batch of solution.
I take a 5-gallon bucket, put an empty net pot on top, take the shower hose attachment and fill to the bottom of the net pot. Then I add the SMS-90 and Grow, take a whisk and mix, and add vinegar to drop the pH (my tap water starts at about 8.0 pH and I add about a tablespoon of vinegar). I put the plant back on top of its bucket in the growing area and then pour the new solution over the growing media so that I can cover all of the media (Grow Stones) with the solution and walk away. I just checked the pH of one of the buckets before writing this and after one week, the pH is still where I want it.
I spent a year once working in a college chemistry lab when I was studying chemistry in college (I am NOT a chemist). Late one night, I needed to adjust the pH and the stores were all closed and even Amazon could not deliver anything on time....so, I used my old knowledge of vinegar vs. baking soda and have been happy ever since. And the vinegar makes a great bi bim bop sauce!! I have very serious epilepsy and would rather use vinegar/lemon than battery acid:) But maybe if I had finished that chemistry degree, I would have those concerns:))
Yeah, malt vinegar would have a lot of carbs, which would mess with PH in weird ways.so long as its not malt its good mate.
FenderSuper said:Battery acid scares me. What other chemicals are in it?
Thank you! I'll still stick with white vinegar. Easier to control.Batter electrolyte, also known as battery acid, is virgin, high purity sulfuric acid diluted to ~33% H2SO4 in deionized water.
It's the real thing.We could always turn to "Coke" it's PH is pretty low, plus carbs. Win/Win
This is true, but sulphuric is so much less expensive, readily available, and plants also use sulphur. Honestly, the amounts we're talking about are trivial if not completely inconsequential... unless you're doing something wrong. So the choice of which acid really dilutes down to what one can get for how much money and directly proportional to how rich and lazy one is.Phosphoric acid for PH down, it gives phosphorus to plants.
KOH for PH up, it gives potassium.
Works great.
Here in Bulgaria both acids are the same price. $5 for 1 liter "pure for analysis" grade.This is true, but sulphuric is so much less expensive, readily available, and plants also use sulphur.

In America common automotive 5.77 liters of battery acid is available at any local auto parts store for around $26. It's a 33.5% concentration so roughly $14/liter. Both the 98% H2SO4 and 85% food grade phosphoric are $27.12/quart online from Duda.Here in Bulgaria both acids are the same price. $5 for 1 liter "pure for analysis" grade.
isnt the dude organic? he cant use PhosAcid if he is sadly bro and if one already has P in feeds, adding more is to literally widen the pool of fixed P in the media, meaning one must add ever larger soluble pools which also compound the matter. Phosphate pollution is a serious problem for water systems.Phosphoric acid for PH down, it gives phosphorus to plants.

Please don’t use vinegar very often. Contains acetic acid, which converts to acetaldehydes, to much is bad for plants. Lemon juice in a pinch, battery acid(sulphuric acid) does work, but can build up sulphate and sulphate salts. However phosphoric acid is the most benign for your girls. Breaks down into phosphate compounds which plants use, without causing high levels of salts.Food grade white vinegar or apple cider vinegar for ph down.

True, but all acids can cause salts to form. It’s part of their innate physical properties. Phosphoric has more compounds that plants like. That’s why they removed phosphates from detergents many years ago. Runoff was causing lakes and rivers to bloom with algae.Using diluted sulphuric acid properly to adjust water pH will not cause "sulphate buildup". Plants use sulphur, it's a necessary nutrient.

yes you can, but you run a risk of raising overall Alkalinity and you have to use quite a bit to get a pH increase, you might try SilicaCan use baking soda for ph up
Potassium Hydroxide (KOH) also known as lye, is ideal for pH adjustments. It's beneficial, safe, and easy to use.yes you can, but you run a risk of raising overall Alkalinity and you have to use quite a bit to get a pH increase, you might try Silica
